Central electricity authority Annual Report 2009-10 from Govt. of India or Comfort Letter to this effect was made available to CEA. CEA found this project to be viable in case the project was funded on the aforesaid basis (90% grant). In the event of any change in the funding pattern, the project would require a fresh examination and Techno-economic Clearance for which the Govt. of Mizoram should revert back to CEA. One of the conditions stipulated in TEC letter was that if time gap between TEC and actual start of work is more than 3 years, a fresh TEC of the project would be required. Proposal for funding the project through various agencies was being pursued by the State Govt. On the request of State Govt., validity of TEC had been extended six times, last one being up to 8.11.2007. Govt. of Mizoram on 21.08.2007 requested for further extension of TEC indicating that Mizoram was seeking Viability Gap funding for the project. CEA observed that during the last seven years, more hydrological data would have become available necessitating reassessment of power potential. As the Cost Estimates were more than 7 years old, they needed revision. Moreover, Govt. of Mizoram proposed to adopt publicprivate partnership mode for implementation of the project, which would change the funding pattern as well as executing agency. Taking these factors in view, CEA did not consider it appropriate to grant further extension of validity of TEC. The Govt. of Mizoram was informed accordingly vide CEA letter dated 1.10.2007. 11.6.3 Private Sector Projects A) CEA Concurred Projects: a) Demwe Lower HE Project (5x342 + 1x40=1750 MW), Arunachal Pradesh by M/s ADPPL Demwe Lower HE Project was accorded concurrence by CEA on 20.11.2009 for an estimated cost of Rs. 13144.91 Crores (Completion Cost). MoEF has accorded Environmental Clearance to the project on 12.2.10. Forest Clearance is under process. Financial closure is yet to be achieved. b) Dibbin HE Project(2x60=120 MW), Arunachal Pradesh Dibbin HE Project was accorded concurrence by CEA on 04.12.2009 for an estimated cost of Rs. 728.54 Crores (Completion Cost). Environment and Forest Clearance is under process. Financial closure is yet to take place. c) Lower Siang HE Project (9x300= 2700 MW), Arunachal Pradesh by M/s JAPL Lower Siang HE Project was accorded concurrence by CEA on 15.02.2010 for an estimated cost of Rs. 19990.74 Crores (Completion Cost).

EPC contract was placed on M/s BHEL in March, 2010. The project progress has been delayed due to very slow progress on civil construction front. The project is now targeted for commissioning in October 2010. b) Bongaigaon TPS (3x250MW): Project is being executed by M/s NTPC at Salakati, Kokrajhar District of Assam. MoEF clearance has been obtained and coal linkage for the project has been accorded by Ministry of Coal. Order of Main Plant Package has been placed on M/s BHEL in February, 2008. Boiler drum has been lifted in January, 2010 and Condenser erection is also under progress for Unit-1. Boiler erection has started for Unit-2 in March, 2010 and for Unit-3, it is expected to start by June, 2010. The constraints being faced in project execution include slow progress of civil works and law & order problem. The anticipated dates of commissioning for Unit-1, 2 & 3 are July, 2011, January, 2012 and March, 2012 (Best Effort Basis) respectively. c) Tripura CCPP (2x 363.3 MW): Project is being executed by joint venture of ONGC, Govt. of Tripura & Infrastructure Leasing and Finance Services (IL&FS) at Palatana, Tripura. Main Plant Order has been placed on M/s BHEL in June, 2008. Project is delayed due to problem in transportation of heavy equipments to site, transmission lines/ power evacuation/ start-up power and finalization of Feasibility Report for infrastructure requirement for use of Ashuganj Port & land route in Bangladesh to reduce time of transportation of machinery to site. The project is likely to be commissioned in 12 th Plan. d) Baramura Gas Based Project, Unit-5 (1x21 MW) The project is an extension unit being executed by Tripura State Electricity Corporation Ltd. (TSECL) in District Agartala, Tripura. EPC contract was awarded to M/s BHEL in March, 2008 with a target date of commissioning as November, 2009.
